This handmade necklace is made by skilled artisans in Japan - made through a process that involves melting glass with a torch. Once the glass is in a molten state, the piece is formed by both blowing and shaping with tools and hand movements. Produced by Hario, which is a Japanese company founded in 1921. They were known for producing glass coffeemakers and science instruments before they started creating jewelry. The brand has its own factory in Japan, which is the only place in the country that produces heatproof glass. Their glass has a strong resistance to temperature change and excellent durability against chemicals and shock. Gold plated chain, 16.5"
